==============
There is no "rate of speed."
There's rate, and there's speed, but no rate of speed.
-----------------
Confirmed by the Dept. of Redundancy Dept.
Let x be the Chris' rate, in miles per hour.
Then Hal' rate is 0.6x mph.
In 5 hours, Chris traveled 5x miles; Hal traveled 5*(0.6x) = 3x miles.
The total distance is
5x + 3x = 72 miles, or
8x = 72
x = 72/8 = 9.
Thus Chris' rate is 9 mph; Hal's rate os 0.6*9 = 5.4 mph.
ANSWER. Hal's rate is 5.4 miles per hour.
